    Abstract:
    AIM: A previous study on a small number of patients showed that low skin temperature of the hands, the so called "cold hands sign", may be useful for distinguishing multiple system atrophy (MSA) from Parkinson's disease (PD). We have further investigated skin temperature of the hand in a larger number of patients. METHODS: Skin temperature on the palm was measured in 50 MSA (11 MSA-P and 39 MSA-C patients) and 50 PD patients, and 25 normal healthy subjects. RESULTS: Palm skin temperature was significantly lower in MSA patients (32.0 ± 2.7 °C) than in controls (34.1 ± 0.9 °C, p = 0.0002), but was not different compared with the PD group (32.9 ± 1.8 °C, p = 0.06). Temperatures of <28 °C were observed in 3 MSA patients (6%) and none of the PD patients and controls. There was no significant difference in palm skin temperature between patients with and without orthostatic hypotension for each patient group, or between MSA-P and MSA-C patients. CONCLUSION: The cold hand (<28 °C) is a useful marker for distinguishing MSA from PD, but it is not common in MSA patients, and its sensitivity may be low for differentiating between MSA and PD.
